as.mids.update: Slightly edited version of as.mids() from mice package

In jenniferthompson/JTHelpers: Personal Helper Functions, Some Related to rms Package

Description

The original function relies on data being sorted by .imp to work properly. This is problematic in data sets created manually - say, calculating summary statistics using original + imputed data, where the final data set we want to combine does not have an .imp column. Original function by Stef van Buuren, with detective work and changes by Cole Beck. See this analysis for a full example.

Usage

as.mids.update(data, .imp = 1, .id = 2)

Arguments

data	A multiply imputed data set in long format
.imp	Mandatory column indicator for the multiple imputation stream, where 0 indicates the incomplete data and 1 through m indicate the m multiple imputation streams. Default is 1.
.id	Optional column indicator for the row numbers. Default is 2.
